The couple that gigs together, stays together.
Lee Hyori and Lee Sang Soon spent a romantic evening together on January 17 - watching their close friend Kim Dong Ryul's concert.
The two sat side-by-side at the Sejong Center for the Performing Arts in Seul, clapping and cheering for their friend of almost 15 years.
An onlooker says: "They were enjoying the show and she put her head in his shoulder a few times. They looked really cute."
Ryul, 38, performed a number of his hit songs, including "The Truth in Wine" and "An Essay of a Memory", before thanking his audience for their support.
"It's the first day of my encore concert, but I'm already about to cry," he said.
Ironically, it was Ryul that Lee Hyori, 33, was (falsely) linked with before before her relationship with 38-year-old Lee Sang Soon became public
This is the first time the couple, who have been dating since summer 2011, dated in public since their Christmas holiday trip to Hawaii and LA.
